le it known that' l, FREDERICK l). FRY, a citizen of the ll'nited States, residing at Danbury, in the county of Fairlield and State ol' 5 (lollneeticut, have invented certain new and ehines; and I do hereby declare the 'following' to be a full, clear, and exact description ol'the invention, such as will enable others skilled use the same.

My invention relates to the manufacture of io in the art to which it appertains to make and em'responding with Fig. l2. Figs. It, l5, 1U, 1T, and IS are detail viewsy illustratinj.;l the eonstruetimi nl' the eutliug device. Fig'. 1t)

Fig. 22 illustrates in plan and side elevation l the movable member ol a pair of holdilig-jaws hat-wires and similar articles, and has for its object to produce a machine that will sever 15 the hat-wires from the roll of wire that is fed to the machine, and will impart a peculiar twist to cach wire, so that when taken from the machine eaeh piece of wire will have been l ot' a twisting-head detached.

bent to approximately the shape of a finished having the required set for the front and rear hat-wire, the sides being highest and the ends detached. Fig'. 2li is a side view of one of the twisting-heads. showing also the adjustinggears beneath furthetwisting-headsandholding-jaw standards; Fig. il, an edge view of one of the twisting-heads detaelnal; Fig. E25, a

` eentral section corresponding with Fig. 24.

of the hat-brim, the amount of set dependp ing upon the amount of twist imparted to the wire. In order to produce wires of this class 2 5 of uniform size, shape, and set, and at great speed, Ihave devised the novel machine which I will now describe referrinfr bv numbers to the accompanying drawings, forming part of l collar which operates the brake, and Fig. 34 8o this speeifieat ion, in which- 4o illustrating` themanner of adjustingthe holding-jaws and the twisting-heads. Figs. S, El, and 1,0 are respeetivelya side elevation, front elevation, and plan view of the sliding feeding device, the jaws being' in the closed position. Fig. 11 is a plan view corresponding` with Fig. 10, except` that the jaws are in the opened position; Fig. 12,21 side view of the stationary standard earryingthe left holdin jaws, the View being from the right` in Figs. 1 and 3, the View also showing the operation Figure 1 is a front elevation of the entire machine; Fig. 2, a rear elevation thereof; Fig. j

of the cutting device; Fig. 13, an edge view Figs. 2li, 27, and 2S are detail views of parts the brake detached. Fig. 3l) illustrates in both end and side elevation the movable jaw of one of the twisting-heads detached. Fig. 31 illustrates in a similar manner the stationary jaw of one of the twisting-heads detached.

Fig. 252 illustrates the guide in each twistinghead through which the wire passes, and in which the jaws are placed transversely. Fig. 33 illustrates in end and side elevation the is a detail of the twisting-gear.

Similar numbers denote the same parts wherever thea` appear in the drawings.

1 denotes frame-work, supported by legs 2,

both frame-work and legs being of an)v suitable, or preferred construction. 3 is the main shaft, journaled underthc frame-work, power being applied by a belt (not shown) running over a pulley, i, on` said shaft'. i

5, li, T, S, l', and l() are cams on shaft 3, the 9o twisting-heads, and lO operates the cutting device. 'lhe construction and operation of these parts and the intermediate connections between the operative parts and the cams will now be described in detail.

1l is the standard which. carries the sia` loc tionary holdiughjawm;

1;), standards carrying movable holding-Jaws, and 13 standards can Fig. 29 shows 7o rying the twisting-hez'tds. The adj ustnicnt of L standards 12 and 13 will be described later in connection with the sliding feeding device.

Turning new to Figs. 19 to 22, inclusive, l will describe the construction and operation of the holding-jaws carried by standards 12. i lt should be noticed. however, that thc construction and operation of the holding-jaws carried by standard 1l is precisely thc same as those carried by standards 12, the only difference being that standard 11 is not movable, and that this standard also carries thc Q cutting device, all ot' which will be morct'ully explained.

14 denotes side plates, which are firmly sccured to standards 11 and one to standard 12. 'lhe standards are provided with holes l5, in which a rock-shaft, 1G, is jonrnaled.

17 denotes the stationary holding jaws, three in number, which arc rigidly secured to blocks 1S between the side plates.

19 denotes the movable holding-jaws, which are carried by oscillating plates 20, pivoted between the side plates. as clearly shown in Figs. 19 and 1;. The style of jaws which 1 preferably adopt is clearlyillustrated in Figs. 21 and 22. At the forward ends of the jaws are notches 21,through which the wire passes. l These notches may be made in any suitable form to grasp and hold the wire iirmly.

22 is a plate secured at the side of the stationary jaw, and having inclines 23, which l engage corresponding inclines on the movable l jaw to insure that the jaws registerwhen they are closed together and to prevent the possiy bility of the wire slipping out when the jaws l are at their open position. The movable jaws, l three in number, are all operated by means of cams 24 on rock-shaft1l3, the action of said cams being to force the jaws tightly upon the wire when the cam is oscillated toward the left, as in Fig. 19. When the backward movement of the rock-shaft and cams takes place, the jaws open instantly, oscillating plates 20 being so pivoted as to drop tothe opened position as soon as the cam moves backward. A spring may, of course, be inserted to throw the jaw to the open position if desired. This, being' a common expedient, has not been illustrated in the drawings. The cams are secured to shaft 16 by means of splines 524, which engage a groove in the rock-shaft, leaving the cams operating in connection with the movable standards free to slide on said rock-shaft.

25 denotes a crank-arm secured to the rockshaft, and connected by means ot' a rod, 26,11) a lever, ',pivoted to a suitable portion ofthe machine, as at :'38, (see Fig. 4,) and having at its inner end a roller engaging a groove (not shown) in cam 7, the groove being so laid out that by means of the intermediate connections just described each rotation of cam T will impart a forward-and-backward movement to rock-sh ai t 1l), thereby closing the jaws and opening them again, the machine being i so organized in this instance that the movei ments of the rock-shaft toward the front in Figs. 1 and 3 act to open the jaws, and the movements toward the back or toward the left in Fig. 19 act to close them.

Turning now to Figs. 225 to 34, inclusive,l will describe the construction and operation of one of the twisting-heads.

2 denotes the stationary twisting-jaw, and :ill the movable twisting-jaw. 'Phe grasping lsurface of these jaws is preferably an independent piecc of chilled steel dovetailcd into place, as clearly shown in Figs. 3() and 31. One of the men1bers-in the present instance the stationary j aw-is provided with plates 31, having inclines f2, which are engaged by corresponding inclines on the movable jaw toinsure that the jaws register when they are closed together and to prevent the possibility ot' the wire slipping out when the jaws are at their open position. The jaws are provided with notches in their grasping-surl'aces, in which the wire lies as it is grasped.

33 denotes a sleeve, having a longitudinal opening, 34, through which the wire passes, and a transverse opening, 35,in which the jaws lie. The opposite ends of the sleeve are journaled in side plates, 3U, which are bolted rigidly to standards 13. The lower ends of the side plates are made thicker and are providtd with recesses 37 to receive brakes 38.

J ust within the side pieces are disks 39, which, for convenience in description, I have termed outer disks, each of which is provided with a central opening through which i the sleeve passes and an eccentric slot, 40.

These slots are engaged by rollers 41, carried i by pins projecting from the ends of the movable jaws. (See Fig. 30.) Just within disks 39 are disks 42, which I term the inner disks, also provided with central openings, through which the sleeve passes, and with slots 43, extending across the central openings in which the jaws lie. Between disks 42 is a i pinion,44, having a central opening similar to the disks through which the sleeve passes, and a slot, 45, to receive the jaws, this slot being similar to slots 43 in the inner disks, except that the portion of said slot which receives the movable jaw is not as long as the slots in the disks, the movable jaw being provided with a notch, 46, the bottom of which engages the end of slot 45 in the pinion, the portions of the movable jaw on the opposite sides ot' the notch engaging the longer slots 43 in the disks, so that the parts are held firmly together when assembled. The twisting-heads are operated by gears 47 on oscillating shaft 4S, which engage pinions 44.

4Q is a pinion on shaft 4S, which is engaged by a segmental gear, 50. Shaft-i8 is journaled in brackets 51, which project backward from the frame-work, and the segmental gear is rigidly attached to a short shat't journaled in a box, 52, which is also carried by a bracket projecting from the frame-work.

53 is an arm made integral with and projecting backward from the segmental gear and provided with a slot, 54, for the attach- IOO IIO

ment ot' a rod, 55. The lower end of this rod is pivoted to an arm, 56, projecting; outward from a slide, 57, which is adapted to move vertically in ways 58 in a bracket, 5S, depending from the fram e-work of the machine, as clearly shown in Fig. 6*. Slot 5i is formed in an are ot` acircleof which the pivotal point of rod 55 to arm 56 is the center. A bolt, 59, passes through the rod and through slot 5l,

and is engaged by a lock-nut,60,whcreby the parts are locked inposition after adjustment.

6l is a gage on arm 53, by which bolt 5ft is set to give any desired number of turns or fractional parts ot' turns to the wire in operation.

It will of course be understood that the farther inward rod 55 is sei in slot 54 the greater will be the oscillation of the segmental gear and the greater the amount of twist given to the wire. As shown in Figs. 5 and (S, rod 55 is set to give the least possible twist to the wire. It is desirable that this adjustment should be effected in as simple a manner as possible, for the reasons that no two coils of wire work just alike, and that changes in the styles of hats necessitate frequent changes in the set of the wires.

, Vertical reeiprocatory motion is imparted to the slide by means of a roller, '2, (see dotted lines, Fig. 5,) carried by a pin at the lower end thereof and engaging groove 63, in cam 8 on the main shaft. It will be seen that each rotation of cam 8 causes an ui'iward-and-downward movement of slide 57, which in turn causes an oscillation in each direction ot' the segmental gear and, through the intermediate connecting mechanism just described, an oscillation in each direction ot' the twistingheads, it being of course understood that the two twisting-heads are of identically the same construction. The brake is operated by means of rock-shaft (il, which is journaled in the 1 standards ll and l2,which carry the holdingjaws. Fig. 4) is a crank-arm, 65. A rod, titi, connects the crank-arm with a slide, (57, moving in ways at the end of the frame-work. (See dotted lilies, Fig. l.) A roller, 68, carried by a pin at the lower end of the slide, engages a groove in cam 9, the construction and arrangement being such that each rotation of cam i) will cause an oscillation ot rock-shaft tit in each direction, whereby the brake is raised and lowered.

Turning again to Figs. :23, "2l, and :25, the connection of the brake with the rock-shaft will be clearly shown.

69 is a sleeve on the rock-shaft, which lies loosely in an opening, 70, in standard 13. The rock-shaft is provided with a groove and the sleeve with a key or feather, 7l, engaging said groove, whereby the sleeve is secu rely locked to the rock-shaft to turn therewith, but at the same time is left t'ree to slide longitndinall thereofI in adjusting' the twisting-heads, as will presently be explained.

A17;? is a link, the opposite ends of which are At the outer end of this shaft (see vomit-fied to the sleeve and to the brake, whereby the latter is forced upward and downward bythe oscillation of the rock-shaft.

'lhe operation of this portion of the machine independently ol the feeding and cutting devices briefly as follows: After the wire has heen passed through the three pairs of hold i iig-jaws and through the two twistingheads, the lirst portion of the mechanism to engage the wire is the three pairs of holdingjaws aetuated by cams :Il on rock-shaft lf3. An inst ant laterthe brakes, actuated by rockshal't tj l, are l'oreed upward and engage the peripheries of the outer disks, 3E), thereby locking said disks for an instant against rotary movement. ly this time the segmental gear, actuated by cam fi and slide 57,will have begun to turn, oscillating shaft 48, carrying gears 4T, engaging pinions 4l. It will, of course, be understood from Figs. 25 to 34, inclusive, and the description already given that inner disks, ,li, must rotate with the pinion and will carry the jaws around with them. As outer disks, 39, are held against rotation by the brakes, it follows that the rotation of the jaws carried by the inner disks and the pinion must cause rollers 4l, carried by pins at the ends ot the movable jaws, to travel inward in eccentric slots JJ) in the outer disks, thereby clamping the movable jaws down tirmly upon the wire, this position being clearly shown in Figs. 2S and 25. An instant later, through the action ot cam il, the intermediate mechanism, and rock-shaft di, the brakes will be released and will drop away from the outer disks, leaving said disks freeto turn with the inner disks and thc pinion, but without. releasing the grip ol' the jaws upon the wire. As the piece of wire heilig acted upon is now clamped iirmly by the three pairs ol.' holding-jaws, and also elan'iped tirmly by the jaws in the twisting-heads midway between each pair of holding-jaws, it Follows that the wire must be twisted by the rotation of the twisting-heads so long as the movement ot' the oscillating' shaft ld in that direction continues. The action ot cams 5% and Si is so timed that at the instant the oscillation oi' shaft `is in that direction ceases and the return movement coinmenees the brakes actuated by cam .i will again engage the outer disks and lock them t'or an instant against movementwith the innen-disks, pinion, and jaws. This second locking of the outer disks will canse rollers il to travel outward in eccentric slots it), thereby throwing the movable jaw outot' contact with the wire, so that the entire twisting-head is l'ree to rotate about the wire, but without contnet therewith during the backward movement. Vllle holding-jaws, actuated by rockshaft lli, cam T,and intermediate mechanism, already l'ully deserilmd, release the wire an instant before the jaws in the twisting-heads release it, so that the wire is now free. Just bcl'ore the releasing oi' the wire by the holding-jaws and the jaws of the twisting-heads IOO t ceases the feeding mechanism, or, as it may be termed, the sliding,fceding, and measuring device, will have moved forward and seized the end of the wire.

Turning now to Figs. L), S. 0, 10, and l1, the sliding feeding device will be found clearly upon the main shaft, each rotation of said illustrated. This device consists o1' upper and i lower plates, Til and TTL, and a standard, T5, to which both plates are secured. plate is provided with downwardly-projecting flanges 76, which rest against the outer edges ofthe top of the frame-work, being held in position by plates 7T, secured to the bottom The lower thereof, which, in connection with the flanges 1 and lower plate, inclose tianges 78 at the edges of the frame-work, this construction being clearly shown in Fig. 23, which illustrates it as applied to one of the twisting-heads, the

construction of this portion of the sliding feeding device, the standards of the twistingheads, and the standards of the holdingclamps being the same.

79 denotes the feedjaws, which are pivoted to the upper plate and are held at their open position by means of springs S0, bearing against their shanks, as clearly shown in Figs. 10 and 11.

81 is a shaft journaled in the upper and lower plates and having at its upper end an oval cam, S2, lying between the shanks of the jaws and actin g to clamp the jaws firmly upon the wire when the greatest diameter of the cam is turned transversely to the Shanks, as shown in Fig. 10.

is a pin projecting outward fromshaft 91 and adapted to be engaged by fingers S4 and S5, projecting upward from a longitudinally-sliding shaft, S6. This shaft maybe reeiprocated in any suitable manner. In the present instancel haveshown it as connected by means of an arm, S7, with a sliding shaft, 8S, held in suitable guides, 80, at the side of the frame-work.

.(10 is a lever pivoted to a bracket, J1, depending from the frame-work. The upper end of this lever is connected by a link, 02,

with the rear end of sliding shaft 8S, and is provided at its lower end with a roller, (indicated in Fig. 1.) which engages a groove, 025, in cam 6. The groove is so laid out that each rotation of cam (i will cause a movement of shafts 'lhe inner end 8o' and S8 in each direction. of shaft Sti supported inaplate, 91, attached to the standard l l of the stationary holdingclamp, and its outer end is supported in a bracket, .05, at the outer end of the framework. The sliding feeding device is caused to reciprocate in the manner which lwillnow d escribe.

titi (see Figs. 1 and 2) is a rod the outerend of which is pivoted to the inner end of a lever,

0T, and the inner end to the upper end of an cam acting to impart a movement of said levcr in each direction. Lever 071s fulerumed on an adjustable block, 102, supported in a guide, 103, under the f rame-work. Lever 97 is provided with a slot, 104, having at its side a gage, 105, the purpose of which will presently be explained.

1,06 is a bolt passing` loosely 'through block 102 and slot 104, and 10T is a lock-nut engaging the end of the bolt and adapted to be screwed down upon lever 07, thereby clamping it tirmly to the bolt, so that the bolt will turn in the block when the lever oseillates. At the outer end of lever 0T is a link, 108, the inner end of which is pivoted to any suitable portion of the sliding feeding device-in the present instance standard 75. As shown in Figs. 1 and 2, the sliding feeding device is at its retracted position. A half-rotation of cam 5 by lneans of the intermediate mechanism just described will throw the sliding feeding device to the opposite extreme of its movement-that is, clear forward to standard 11, which carries the stationary holding-jaws and the cutter.

Turning now to Figs. 12 to 1S, inclusive, l will describe the operation of the cutter. As

t already stated, standard 1l is similar in construction to standards 12; but only one plate 14 is used, plate 109 being substituted for the other plate 14, and attached to the standard in the same manner. Plate 10%, is provided with a threaded opening, 110, which is engaged by the inner end of threaded sleeve 111 and with transverse slots 112, which receive pins 113 on the cutters 141. These cutters slide in transverse groove 115 in a plate, 116, which is rigidly secured to plate 109, the position of the parts after assembling being clearly shown in Fig. 13.

117 is a disk journaled on sleeve 111 and provided with curved slots 118. This disk turns freely on the smooth portions of the sleeve, and is held in position thereon by ange 119 at the outer end thereof. Pins 133 on the cutters pass entirely through slots 112 in plate 109 and engage the curved slots 118 in the disk. The disk is oseillated on the sleeve to move the cutters in and out by means of an arm, 120, rigidly secured thereto, the outer end of which is pivoted to a rod, 121. The lower end of the rod is pivoted to the outer end of a lever, 122, which is itself pivoted to one of the legs of the machine, as shown in Fig. 2. The inner end of this lever bears against eccentric cam 10 on the main shaft, the weight of the inner end of the lever being sufficient to draw it down when the short diameter of the eccentric cam is at the top. Vhen the long diameter of the eccentric cam moves upward, its actionis to raise the inner end of lever 1:22, which of course throws down the outer end,and by means of arm 120 turns disk 117 on the sleeve, and by means of the engagement of pins 113 with the curved slot-s in the disk forces the cutters inward,

IOO

IID

thereby severing the wire. It will be seen that each rotation of eccentric cam l0 moves the cutters to their retracted position, severs the twisted wire, and then causes the cutters to move back to their retracted position. At the instant the completed wire severed the sliding feeding device will move up to the cut ters, the jaws thereof' passing into sleeve lil. By this time the cutters will have moved to their retracted position, so that the jaws can pass forward through theslccve and through opening 123 in plate l lli close up to holdingjaws 1T and it).

crates the movable holding-jaw in Istandard 11, that there must be a stump of wire left between. the cutters and the holding-jaws after the twisted wirtI has been severed. This stump (not shown in the drawings) is grasped by the leed-jaws Til. The operation of these jaws is as follows: At the instant that the l'eed-jaws,still in their open position, as shown in Fig. 1l, have parsed through sleeve lll and into opening lfi in plate lili It will be noticed i'roin the l. position of the cutters and cam il, which oppin on shaft 8l will be engaged by linger 84 on sliding shaft 86, which will at that; iiistant move toward the left, as seen in F ig. l. thereby turning shaft. 8l and ca l y 'ngc-ain S2 from the position shown in Fig. 1l to the position shown in Fig. lll. This closes the jaws firmly upon the wire. As the position of cam 82 at this instant is such that the shanks of both jaws as acted on by springs S0 press equally upon the eam,itfollows that the jaws must remain in the closed position and clamp the wire rmly until they are allowed to open again by the turning of the cam by another movement of sliding shaft Sli. The instant the wire has been grasped by the jaws the rei turn movement of the sliding feeding device commences. This continues until the prede termincd length of wire has been drawn forward through the holding-jaws and twistingheads. The instant the return movementkthat is, the movement toward the left in Fig.

l-of the sliding feeding device is completed the three pairs of holding-jaws engage the wire.

The jaws in the'twisting-heads also engage it and commence -the twisting` of a l wire by the cutters and the releasing` by the t feed-jaws being practically simultaneous. The completed wires may be taken from the machine by an attendant or may be allowed to drop. These movements are continuously repeated and produce perfectly-twisted wires of any desired size at a high rate of speed.

As already stated, the twisting' of the wire acts to produce the desired amount of set at the front and rear of the hat-brim. Fingers 84E and S5 ai'e secured to shaft 8G by setscrcws, so that they may be readily adjusted by loosening' the set-screws, moving the lingers on the shalt` and again tightening up the set-screws.

lt will be apparent that a certain relative ad justinent ot' the twistingheads relatively to the movable holdin g-jaws must be maintained at all times, and that the throw of the sliding feeding device must. be equal to the distance between the right pair of holding-jaws and the stationaryY hohling-jaws-tliat is to say, the exact amount ot' wire required for each init-wire musir be drawn l'orwai'd by cach return movement ot' the sliding Feedingdeviceand no matter what may be the length of the wire that is to be made it must be gripped at; both ends and midway between the ends, and the two twisting-heads must act midway bctween the pairs oli` holding-jaws, one twisting-head being located atY all times midway between the stationary holding-jaws and the middle pair of the movable holdingjaws, and the other twisting-heads midway between the other pairs of movable holding-jaws. By niovable" i mean capable ol being moved, it' being of course understood that the position oi the two pairs ot' movable holding-jaws is only changed when the lengthof wire produced by the machine is changed.

Itisof course quite practicable to iiiv the adjustments independently of each other. I have, however, provided an adjusting device which, by slight movement in either direction, will change the adjustment ol" the two pairs ot' movable holding-jaws and the two twisting-heads, and will also change the throw of the sliding feeding device, so that it will always corrcspond with the distance between the right movable holding-jaws and the stationary holdingjaws.

As already explained, the standards which carry the twisting-heads and the movable holding-jaws slide upon the top of the l'ramework, which may be ot' any preferred construction, there being, preferably, two side pieces, as shown in Fig. Eil. Each of theinovable standards l2 and lil provided with a downwardlyprojectinglug, 124-, to which racks are pivoted, the rack pivoted to the standard carrying the right holdingjaws (seen in dotted lines only in Fig. 7) being denoted by 125, the rack pivotedto the standard carrying the right twisting-head being denoted by liti, the rack pivoted to the standard carrying the central holding-jaws being de noted by 127, and the rack pivoted to the standard carrying the lett twisting-head being denoted by 128. The lugs to which these racks are pivoted are provided with baseplates screwed firmly to the under sides of the standards, one et them heilig shown in Fig. These lugs are so arranged that the racks lie side by side without interference, as shown IOO IIO

IZO

Yregister with lock-nut 1o.".

in Fig. 7. The inner ends o1' these racks eul gage a series of gears on a shaft, 129, jouri naled in the frame-work. These gears are all of a different size,and are so laid out that rol tation of shaft 12H will move the standard ot' the central holding-jaws double the distance l that the standard of the left twisting-head is moved, will move the standard of the right twisting-head double the distance that the standard ot' the central holdingjaws is moved, and will move the standard of the right holding-jaws double the distance that the standard ot the right twisting-head is moved. ln the drawings l have denoted the gear eligaged by rack 1;5 as 130, the gear engaged by rack 120 as ltl, the gear engaged by rack 127 as 132, and the gear engaged by rack 12S as 138. As the distance between the stationary holding-jaws and the right pair of movable holding-jaws must correspond with the throw of the sliding feeding device,l adjust the throw of said device b v the same gear denoted by 125, which adjusts the position of the right holding-jans. 'lhis adjustment is effected by i a rack, 1234, the outer end ot' which is pivoted to adjustable blocks 11.12, and the inner end of vwhich is supported in contact with gear 125 yby a roller, 135, carried by a suitable bracket depending from the Frame-work. (bee dotted lines, Fig. El.)

13o is a disk on the end ot' shaft l2!) at. the front of the machine. 'lhis disk is provided with holes in its periphery to receive a rod for the purpose of turning it to adjust the standards and feeding device, and after adj ustment the parts are locked in position by a pin, 137. which passes through a bracket, 138, secured to the frame-work and engages one of the holes in the periphery of the disk.

Turning for an instant again to Fig. 2, it will be noticed that a gage is provided by the side of the slot in lever 97. It will of course be apparent that in the construction shown the throw of the sliding feeding device will be determined bythe position of the fulcrum of said lever 97. Then it is desired to make a change in the length of wire that is being produced, itis simply necessary to loosen locknut 107 and remove pin 137 from disk 136. The disk is then turned in the direction required to lengthen or shorten the wire. The adjustment is of course made when the holding-jaws and the jaws of the twisting-heads are at their open position and the sliding feeding device is at the extreme ot' its movement toward the right, as seen in lfig. Q-that is, from the rear of the machine. ln this position, and as seen in this figure, rotation of disk 136 and the gears toward the right will, by means of rack 134, move block 102 and bolt 106-. e., the fulcrum of lever '3T-toward the left, and will also move the standards of the twisting-heads and movable holding-jaws toward the right. The exact length of wire that will be formed at any position of the parts is indicated by gage 105, which is marked to Yt'hen thelength l oll wire that it is desired to produce is indicated by the gage, the lock-nut is tightened up to clamp lever JT and bolt 10U together, and pin 1217 is passed through bracket 138 and into one of the holes in the periphery of disk 1156. This locks the parts in position, and the machine is ready for use.

The operation ot the entire machine is briefly as follows: ln starting the machine, wire is passed in from the right, as seen iu Fig. 1,through the three pairs of holding-jaws and the two twisting-heads, and up to, but not necessarily through, the cutters. ll' the machine is started with the parts in this position, the holding-jaws first close upon the wire, grasping it firmly at three places. The brakes in the twisting-heads operate, the jaws in the twisting-heads close upon the wire, and the rotation of the twisting-heads midway between the points at which the wire is held by the holding-jaws twists the wire. At the conclusion oi the twisting operation the brakes again act. the jaws in the twisting-heads release the wire, the holding-jaws release the wire, and while the twisting-h eads are being turned backward the sliding feeding device advances, the feedjaws grasp the end of the wire, the return movement of the feeding device takes place, and the portion of the wire which has just been twisted is drawn past the cutters, and a su'tiicient quantity of the wire to form another hat-wire is drawn forward ready to be grasped by the holding-jaws and the twisting-heads. At the instant that the return movement of the feeding device is completed the holdingjaws and the jaws in the twisting-heads again grasp the wire, the operation of twisting the new wire commences, and at the same instant the completed wire is severed by the cutters and released by the fixed jaws, these movements being continuously repeated. Each rotation of the main shaft thus acts to measure the length of a single hat-wire, to sever the wire just completed, and to twist a second wire.
